城市生态系统网络稳定性的理论计算与分析

Theoretical computation and analysis of the stability of urban ecological system network

为了计算城市生态系统网络的稳定性,分析了城市生态系统网络的构成特点,确定了以网络基元为基本分析单位的网络稳定性计算思路,定义了标准网络基元及网络基元与网络整体稳定性的计算方法.虚拟生态系统网络样例计算证明该方法可行,并具体计算了实际三线城市生态系统网络的稳定性,计算结果合理.

In order to calculate the stability of urban ecosystem network, the structural characteristics of urban ecological system network is first analyzed, and the idea of computing the network stability is proposed based on the network unit.Then, the standard network unit and the concrete calculation method of its stability are defined;also the calculation method of overall network is discussed.At last, an example of ideal ecological system network is simulated which shows that the calculation method is feasible, and the-method is further applied to the actual calculation of the third-tier urban ecological system network and a reasona- ble result is obtained.
